''Killer Nun'' (1978) was produced in Italy. It features Anita Ekberg as Sister Gertrude, who is recovering from the removal of a brain tumor, although her Mother Superior (Alida Valli) dismisses Sister Gertrude's fears about a rushed recovery. Unfortunately, soon enough, it becomes clear that Sister Gertrude's fears were legitimate, as the hapless nun spirals into psychosis and addiction to morphine and heroin at the geriatric hospital where she works.
